KUSA - Teachers and staff of Arapahoe High School went back to work Monday. Students will return to class Tuesday.
Students will find special Post It notes on their lockers with messages like "you are important," "you are loved," and "we are all Warrior strong."
This will be the first time classes are held since the shooting on December 13.
Finals will be held on Wednesday and Thursday, but the principal says they're optional and only if students want to improve their grades.
The shooting left two students dead, Claire Davis and the gunman.
